Third, understanding more about women's drinking can increase knowl edge about the factors that influence drinking behavior and drinkingrelated problems more generally. Trying to un derstand why women as a group drink less than men, but also why some women drink more than other women, can help to clarify how gender and gender roles (i.e., social expectations about how women and men should behave) affect the drinking behavior of both women and men.
In this article, we review general trends in women's alcohol consumption over the last 20 years and present data from a 10year longitudinal study conducted between 1981 and 1991. We describe the influences of some demographic variables on women's drinking and identify person al and social risk factors for problem drinking. 4 Finally, we suggest implica tions for prevention of alcohol problems and make some recommendations for future research on women's drinking.

TRENDS IN WOMEN'S DRINKING
Not only have drinking patterns among women varied across different periods in 4 Terms such as "problem drinking," "frequent light drink ing," or "moderate drinking" are defined as they are used history, but society's concern about women's drinking has varied even more (Fillmore 1984). During the 1970's, for example, media reports and public perception pre sumed that drinking among North American women was increasing dramatically and approaching the drinking levels of men.
To test the notion that women's drink ing levels were converging on those of men over the last two decades, Hilton (1988Hilton ( ) compared 11 surveys conducted between 1964Hilton ( and 1984. The study did not detect any major variations in alcohol consumption, although there were fluctua tions in women's drinking behavior with in specific age groups, and the overall drinking (nonabstention) rate was highest in the most recent survey. Yet there was no evidence for a convergence of drinking rates between men and women. In all age groups and across all surveys, men had significantly higher rates of drinking and heavy drinking than women.
In an analysis of a 1983 and a 1988 national survey, Williams and DeBakey (1992) also detected no convergence of drinking behavior of women and men. But contrary to Hilton's study (1988), they observed a trend toward reduced alcohol consumption among both women and men. This trend is consistent with declining alcohol sales in the United States during the 1980's . Among women, the study found increased abstinence and/or decreased heavy drinking in all age groups and in several other demographic subgroups.

Because Hilton's and Williams and
DeBakey's studies used somewhat differ ent criteria to assess drinking and cannot be compared directly, we reanalyzed the 13 surveys used in their studies, two 1990 surveys, and our own 1991 national sur vey. The data (table 1) suggest that changes in women's drinking since 1970 are best described as two trends: a moder ate increase in drinking rates for all age groups during the 1970's, followed by a slight drop during the 1980's for all age groups ). We did not, however, detect any drastic changes in women's drinking behavior. Therefore, none of these three studies supports the perception of a dramatic increase in wom en's drinking since the 1970's.

LONGITUDINAL ANALYSIS OF WOMEN'S DRINKING, 1981-1991
In addition to looking at time trends of drinking behavior in the general female population, we analyzed changes in drink ing patterns and drinkingrelated prob lems of individual women over a period of 10 years (Wilsnack 1993). For this study, a sample of 911 women was first interviewed in 1981. In 1986, 300 of these women were reinterviewed, and in 1991, 696 women from the original sample plus a new sample of 403 women were asked the same questions as in 1981. Drinking behavior was analyzed separately for different age groups.  1971 1972 1973 1973 1974 1975 1976 1979 1981 1983 1984 1988 1990 1990 1991   A comparison of results from the 1981 and 1986 surveys indicates that individu al drinking behavior fluctuates signifi cantly over time ). This can be illustrated with variations in problem drinking over time. (Problem drinking was defined as fulfilling at least two of the following criteria: average alcohol consumption of two or more standard drinks per day, one or more drinking problems during the past year, or one or more alcohol dependence symptoms during the past year. 5 ) Eleven percent of women drinkers who did not report indicators of problem drinking in 1981 showed some of these indicators 5 years later. And onethird of the women who were problem drinkers in 1981 did not fall into that category in 1986.
The greatest changes in drinking behavior were found among women in the 5 These criteria do not attempt to approximate a clinical diagnosis of alcohol abuse or alcohol depen dence; they merely identify a group of women who may be experiencing problems related to their use of alcohol. The threshold for each criterion is relatively low. However, requiring at least two of the three criteria identifies about 10 percent of the women sampled as problem drinkers, a percentage that falls in the middle of estimated rates of problem drinking among U.S. women during the two decades preceding the 1981 survey (Ferrence 1980). youngest age group (21 to 34 years). Fillmore and colleagues (1991) noted a similar trend in their analysis of surveys from 15 countries. This tendency of younger women to move into and out of problemdrinking patterns may be influ enced by changes in drinking contexts, drinking partners, and social roles (e.g., employment, marriage, and parenthood) common in this age group.
A comparison of data from the 1981 and 1991 surveys showed modest declines in most measures of drinking behavior. (Some data from the 1981 and 1991 surveys are summarized in table 2.) There were no significant changes in drinking rates (nonabstention) during the study period. The proportion of women who were heavy drinkers, however, was lower in all age groups in 1991 than in 1981. There also was a decline in heavy episod ic drinking (six or more drinks per drink ing occasion) among women drinkers in most age groups.
Despite the reduction of heavy drink ing episodes, women drinkers under age 40 became more likely to report intoxica tion. This finding may point to the suc cess of alcohol education campaigns in the last decade: women now may be more alert to the intoxicating effects of alcohol and therefore not only may report intoxi cation more readily but also may reduce their drinking levels because of perceived effects of alcohol.

SUBGROUP VARIATIONS
Many studies have shown that drinking behavior is influenced by both an individ ual's personality and demographic char acteristics, such as age, marital status, employment status, and race and ethnici ty. Associations between these factors and women's drinking are discussed below.
Because of necessary limitations to study designs, epidemiologic studies often can analyze relationships between drinking behavior and only a few demo graphic factors. One has to keep in mind, though, that a person's drinking behavior is determined by more than just a few characteristics. Only the combination of all demographic factors, together with historical and cohort effects and personal or environmental risk factors (e.g., genet ic background and family environment), can explain individual drinking patterns.

Age
Like gender, age is a strong predictor of drinking behavior. Numerous surveys have shown that younger women have higher rates of heavy drinking and alcohol related problems than older women (see tables 1 and 2). For instance, in our 1981 and 1991 surveys, women ages 21 to 30 had the highest rates of intoxication, drinking problems, heavy episodic drink ing, and alcohol dependence symptoms. Women over 60 had the lowest rates for all these drinking variables ; see table 2 and figure 1). Similar differences in drink ing, heavy drinking, and drinkingrelated problems across age groups were found in a 1984 national survey (Hilton 1991).
These studies also suggest that younger and older women have different styles of drinking. Younger women tend to engage in heavy episodic drinking that may lead to severe adverse behavioral or social consequences. These can include alcoholimpaired driving and alcohol related car crashes, both of which have shown dramatic recent increases among younger women (Popkin 1991).
Drinking in older women, however, seems to be characterized by frequent light or moderate drinking. In the 1984 survey, for example, daily drinking was at least as common among women drinkers over 60 as among drinkers in other age groups (Hilton 1991). A 1989 Canadian survey confirmed that among older wom en drinkers, the frequency of drinking does not decline with age (Health and Welfare Canada 1990). Despite the over all pattern of abstinence or moderation, however, a substantial number of older women develop alcoholrelated problems. The combined effects of age and gender create some distinctive treatment and prevention needs among these older women who are problem drinkers (Wilsnack et al. in press).

Marital Status
Various surveys have shown associations between a woman's marital status and her drinking behavior (e.g., Clark and Midan ik 1982; . These studies found that nevermarried, divorced, and separated women generally have the highest rates of heavy drinking and drinkingrelated problems; widowed women, the lowest rates; and married women, intermediate rates.

Divorce and Separation.
Although in most surveys heavy drinking and drinking related problems are more prevalent among women who are divorced or sepa rated than among married women (Clark Relationship between the categories of drinking and heavy drinking by women and the demographic characteristics of age, marital status, and employment status. The 1,099 women were interviewed in 1991 as part of the National Longitudinal Study of Women's Drinking. They were classified as "drinking" if they drank any alcohol in the past 12 months and as "heavy drinking" if they drank two or more standard drinks per day during the past 30 days.

Figure 1
and Midanik 1982;, two studies in the mid to late 1980's found somewhat weaker relationships between partnership dissolution and women's drinking (Health and Welfare Canada 1990;Hilton 1991). In both sur veys, the rates of heavier drinking and drinkingrelated problems among di vorced or separated women were similar to those of married women and less than those of women who never had been married. The reasons for this trend remain to be determined. A few longitudinal studies have tried to determine whether women's drinking is a cause, consequence, or accompaniment of divorce and separation. Depending on the individual situation, a woman's drink ing probably can be any one of these: an analysis of divorce rates and alcohol consumption in the United States from 1933 to 1984 concluded that divorce rates influence alcohol consumption but not the reverse (Magura and Shapiro 1988). Sim ilarly, survey data from 1982 to 1988 found that women ages 24 to 32 who divorced or separated during the study period reported increased drinking, whereas those who married or remarried showed decreased drinking (Hanna et al. 1993). A British study, in contrast, sug gested that heavy drinking contributes to partnership dissolution (Power and Estaugh 1990).
Data from our 1981/1986 longitudinal study indicate that the relationship be tween divorce and drinking depends on a woman's history of problem drinking . For women with no indications of problem drinking in 1981, divorce or separation during the study period were marginally associated with an increase in problemdrinking indicators in 1986. Partnership dissolution, therefore, may be a risk factor in women with no prior alcoholrelated problems.
For women who are problem drinkers, however, drinking is a risk factor for subsequent divorce or separation. Women reporting heavy drinking or problem drinking in 1981 were more likely to be divorced or separated in 1986 than were nonproblem drinkers. Somewhat surpris ingly, partnership dissolution led to a reduction in problem drinking for these women, perhaps by removing the woman from a distressing relationship in which partnership problems and excessive drink ing were mutually reinforcing .

Cohabitation.
Another marital status that is strongly associated with women's drinking and drinkingrelated problems is cohabitation. In our 1981 national survey, cohabiting women reported the highest percentage of drinking (100 percent), heavy drinking (18 percent), intoxication, problem consequences, and alcohol de pendence symptoms . A similar result was obtained in the 1991 survey (figure 1), although the drinking and heavy drinking rates both Women working in nontraditional, maledominated occupations reported increased drinking and/or adverse drinking consequences.
declined over the 10year study period. Cohabitation also predicted increases in heavy drinking episodes, intoxication, and drinking problems in the 1981/1986 longi tudinal study, even after controlling for the women's ages and previous drinking levels ).

Employment
During the 1970's, employment outside the home was considered to affect wom en's mental health and drinking behavior adversely, especially when combined with marital or family roles (Johnson 1982). Findings from several surveys conducted in the 1980's have disputed the notion that employment leads to harmful drinking behavior. Despite the fact that most studies reported higher rates of drinking by women employed outside the home, they found no differ ences in heavy drinking or adverse drink ing consequences between employed women and homemakers (Shore 1992 figure 1). Recent survey data are consistent with a new hypothesis that multiple roles, such as family, marriage, and paid employ ment, can be beneficial for women, reduc ing their risks of both mental health and drinking problems (Froberg et al. 1986). Potential reasons for this beneficial effect include increased selfesteem and social support, more responsibilities and perfor mance demands, and increased social monitoring, all of which could discourage excessive alcohol use. This hypothesis is supported by data showing that lack of social roles (e.g., being unmarried or without fulltime employment) or loss of social roles (e.g., a marriage ending or children leaving home) are associated with higher rates of problem drinking in several age groups of women (Wilsnack and Cheloha 1987).
Nontraditional Employment. Whether employment has beneficial or adverse effects on a woman's drinking behavior depends in part on the kind of job she has. In several recent studies, women working in nontraditional, maledominated occu pations reported increased drinking and/ or adverse drinking consequences. For instance, LaRosa (1990) found that highranking women executives were more likely to be drinkers and to drink moderately or heavily than other em ployed women of comparable age and education. In a study by Wilsnack and Wright (1991), women drinkers in occu pations with more than 50 percent male workers scored higher on a problem drinking index than women in female dominated occupations.
The influence of gender composition of coworkers on drinking behavior seems to be specific for women. Men's drinking behavior does not seem to be affected by this factor (HaavioMannila 1987;Wils nack and Wright 1991).
Several interpretations of the relation ship between employment that is nontra ditional to women and increased drinking by women have been suggested. These include peer influences (i.e., women's imitation of the male drinking model), more drinking opportunities in nontradi tional employment settings, stress related to a minority status in maledominated occupations, or the use of drinking as a symbolic expression of power and gender equality .

Unwanted Statuses
Factors such as marital status and em ployment status also can affect a woman's drinking behavior if they reflect a social position she would prefer not to have. Data from our 1981/1986 survey show that an unwanted status (e.g., being unem ployed but wanting a job, being married but experiencing marital distress, or being childless but wanting children) can in crease the risk of problem drinking in women. An unwanted status is associated with increased alcohol consumption and more adverse drinking consequences. This is especially true for drinking wom en who had access to alcohol in their home (Wilsnack 1992). In the 1981 sur vey, the correlation between unwanted statuses and drinking patterns was consid erably stronger in women than in a com parison group of men. The reason for this gender difference is not fully understood.

Race and Ethnicity
Several national surveys have examined ethnic differences in drinking patterns among women and men (e.g., Wilson and Williams 1989), and a national survey conducted in 1984 and 1992 systemati cally oversampled ethnic minority re spondents (Caetano 1991;Herd 1991). In general, these studies have found that among the three major population groups in the United States, white women and men are most likely to drink, African American women and men are least likely, and Hispanic women and men are in between. In all the groups, men have higher levels of drinking and heavy drinking and higher rates of drinking related problems and alcohol disorders than women.
Characteristics that influence drinking behavior, such as age, marital status, and employment status, generally have similar effects across ethnic groups, although some exceptions have been noted. For more information on drinking patterns among minority women, see the article by Caetano, One strong predictor of women's drinking that is valid across ethnic cate gories is the level of acculturation, that is, adaptation of immigrants to the attitudes, values, and behavior of the population they have entered (Gilbert and Collins in press). JapaneseAmerican women, for example, show less abstention and more lighttomoderate drinking than women in Japan (Kitano et al. 1988). Similarly, heavy drinking increases significantly through successive U.S.born generations of MexicanAmerican women (Caetano and Medina Mora 1988).
Most studies of drinking behaviors among ethnic minorities have two draw backs. First, surveys often include sample sizes of minority respondents that are too small to produce reliable findings. The evaluation of less populous minorities, such as AsianAmericans and American Indians, especially is difficult because of this limitation. Studies oversampling these groups are still rare. Second, the surveys often do not consider differences within ethnic categories.
Studies that do assess heterogeneity within ethnic categories find great varia tions of drinking behavior. For instance, a study of AsianAmericans in Los Angeles found that Japanese women were less likely to abstain and more likely to drink heavily than were Chinese, Korean, Filipino, or Vietnamese women (Chi et al. 1989). Similar variations were found among different Hispanic subgroups (Caetano 1988) and among tribal groups of American Indians (May 1989).

Influence of Partner's Drinking
In addition to demographic characteris tics, epidemiological studies of women's drinking have identified other social and personal risk factors for problem drink ing. One important predictor is the drink ing behavior of partners and husbands. Both clinical studies and general popula tion surveys (e.g., Jacob and Bremer 1986;Kolonel and Lee 1981) have found a positive association between women's levels of alcohol consumption and those of their partners.
In our 1981 survey of women and a comparison group of men, the perceived frequency of a spouse's drinking had a stronger association with women's prob lem drinking than with men's problem drinking . The notion of a stronger influence of husbands on their wives' drinking than vice versa is consistent with Haavio Mannila's interpretation (1991) that wom en may imitate the drinking behavior of a "higherstatus" male, whether in the family or in the workplace.
Not just conformity but also discrep ancies in the drinking patterns of marital partners may increase a person's risk for problem drinking. In the 1981 survey, wives reported more intoxication and adverse drinking consequences if they perceived discrepancies between their husbands' drinking and their own than if they perceived drinking patterns as simi lar . A comparable link between discrepant drinking patterns and alcohol problems has been found among men (Gleiberman et al. 1992). It is unclear whether dis crepant drinking patterns of spouses or partners reflect conflicts in a relationship, cause them, or both.

Childhood Sexual Abuse and Relationship Violence
Childhood sexual abuse has been associ ated with women's drinking in both clinical studies and national surveys. The prevalence of incest and other childhood sexual abuse is significantly elevated among women in alcoholism treatment Russell and Wilsnack 1991). In a 1986 general population survey, we found that twice as many women with a history of problem drink ing reported childhood sexual abuse as women without such a history. The expe rience of childhood sexual abuse also predicted the onset of problem drinking in the 1981-1986 study period .
Recent research also is exploring potential links between partnership vio lence toward adult women and their drinking behavior. Several studies have found an association between female drinking and increased victimization in marital violence Kaufman Kantor and Straus 1989). Ac cording to a 1992 U.S. survey of alcohol and family violence, a wife's drinking, whether alone or with her husband, led to more severe violence both by and toward the wife (Kaufman Kantor and Asdigian in press). These studies underscore the need for more attention to relationship violence as both cause and consequence of women's drinking.

Sexual Experience
Women experiencing sexual problems or sexual dysfunctions are at increased risk for chronic problem drinking. When we analyzed possible risk factors for wom en's drinking in our 1981/1986 longitudi nal study, sexual dysfunction was the strongest single predictor of continued problem drinking. The relationship be tween alcohol and female sexuality is discussed in more detail in the article by Norris, Both women and men expect alcohol to enhance sexual experience, a percep tion that may increase alcohol consump tion. In our 1981 survey, for example, 60 percent of women drinkers (especially heavy drinkers) reported that they felt less sexually inhibited after drinking . These effects were reported most frequently by the heaviest drinkers in the study.
Some surveys (see Cooper 1992) have suggested an association between alcohol consumption and increased risky sexual behavior (i.e., unprotected, with multiple partners, or with partners at high risk for HIV/AIDS). However, most studies to date could not establish a direct causal relationship between drink ing and highrisk sexual behavior (Cooper 1992;Leigh 1993). And most women in the 1981 survey reported that drinking did not actually change their sexual behavior (e.g., make them less discriminating in their choice of part ners) . Clearly, additional factors, including characteristics of the woman, her partner, and the social situation, influence the connections between women's drinking and their sexual behavior.

CONCLUSIONS AND FUTURE DIRECTIONS
Analysis of women's drinking over the past 20 years has suggested a moderate increase in alcohol consumption during the 1970's, followed by a slight decline in the 1980's (Hilton 1988;Williams and DeBakey 1992;. Drinking trends among women need to be monitored further to determine whether the decline continues through the 1990's. The decline in women's drinking noted so far seems to be somewhat more gradual or less consistent than the concur rent decline in alcohol sales Wilsnack 1993). Further re search is needed to determine whether the decrease in women's alcohol consumption is happening more slowly than the de crease in men's and, if so, why.
Similar attention must be paid to the changes in drinking patterns among mi nority women. So far, the trend toward reduced alcohol consumption seems to be clearest for white women and less pro nounced among AfricanAmericans and Hispanics (Midanik and Clark 1992;Caetano and Kaskutas 1993). Future studies should address this issue by over sampling minority women, especially women who are heavy drinkers. This is particularly important for minorities, such as AsianAmericans or American Indians, who have been underrepresented in sur veys until now.
The overall decline in women's drinking should not lead to alcohol re search shifting away from women's issues for at least two reasons. First, there are some indications that drinking problems and alcohol disorders may still be increasing in some age groups. Future research must determine whether the higher rates of alcohol problems among younger women found in some studies (e.g., Robins et al. 1988) are a result of increased recognition of alcohol prob lems and a greater willingness to report them or whether the prevalence of these disorders is actually increasing.
Second, if generally decreasing alco hol consumption leads to a shift in drink ing norms and reduced tolerance toward people with alcoholrelated problems (Room 1991), it could become even more difficult than it is at present for women who are problem drinkers to acknowledge and overcome their problems. Such a development would increase the need for gendersensitive prevention and treatment services for these women.
Drinking behavior in women clearly is related to demographic characteristics, such as age, marital status, and employ ment status. Therefore, future prevention and treatment research should focus on specific subgroups as well as the female population in general. Recent research already has identified and addressed some subgroupspecific characteristics of drink ing behavior. More detailed studies are needed to answer questions such as the following and to translate the findings into new prevention strategies: • How can heavy episodic drinking and alcoholimpaired driving be reduced in young women?
• How do divorce and separation affect women's drinking behavior? When do they have beneficial effects and when do they have adverse effects?
• How can the apparent adverse effects of cohabitation on drinking behavior be prevented or addressed?
• When are multiple social roles harmful or protective for women's drinking behavior?
• What effect does the lack of social roles have on drinking? How can this lack be counteracted?
The answers to these questions can lead to prevention and treatment approaches that target specifically the shared or distinct characteristics of both women's and men's drinking behavior and thus improve the effectiveness of intervention for both genders. ■
